In an electric power transmission grid system, switchyard reactors are large inductors installed at substations to help stabilize the power system. For transmission lines, the space between the overhead line and the ground forms a capacitor parallel to transmission line, which causes an increase in voltage as the distance increases.
A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

Switches: to control the flow of electricity, and isolate equipment. [28] The substation busbar: typically a set of three conductors, one for each phase of current. The substation is organized around the buses, and they are connected to incoming lines, transformers, protection equipment, switches, and the outgoing lines. [27] Lightning arresters
A terminal tractor Terminal tractor at the Port of Dover.. A terminal tractor, known in the United States as a shag truck, shunt truck, spotter truck, spotting tractor, yard truck, yard shifter, yard dog, yard goat, yard horse, yard mule, yard jockey, yard spotter, hostler, or mule, is a kind of semi-tractor intended to move semi-trailers within a cargo yard, warehouse facility, or intermodal ...
The 24 kV lines feed a network of 11 substations (12 including the Wayne Junction switchyard) located every 8 to 10 miles (13 to 16 km) along the electrified rail lines. Most branches are short enough to only require a single substation near the end of the line, but the Main and West Trenton lines are long enough to require intermediate ...
In the UK Crane Rental industry in the UK, which is one of the most highly developed crane rental industries in the world, special regulations for health and safety and rental procedures are in place. These are maintained as the CPA regulations. [1] In Europe, European Rental Association is the trade body representing the equipment rental industry.
The inductive reactance is chosen to be low enough for an acceptable voltage drop during normal operation, but high enough to restrict a short circuit to the rating of the switchgear. The amount of protection that a current limiting reactor offers depends upon the percentage increase in impedance that it provides for the system.
